Title

Windows Server 2025 Windows Remote Management (WinRM) client must not use Digest authentication.

Control

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\WinRM\Client\ Value Name: AllowDigest Type: REG_DWORD Value: 0x00000000 (0)

Discussion

Digest authentication is not as strong as other options and may be subject to man-in-the-middle attacks. Disallowing Digest authentication will reduce this potential.
